HVAC Company in Justin, TX
Dalton Heating & Air is the HVAC company in Justin, TX that homeowners call when they want the price in writing before work starts and a guarantee that actually means something.

Call (361) 306-9515 and you’ll get a live person, not a voicemail queue.
Why Justin Homes Are Different
Justin’s housing stock runs from established ranch-style homes on larger lots to newer construction in subdivisions like Fincher Farms and The Preserve at Justin. That mix changes the work. Older systems in 1970s and 1980s homes often run R-22 refrigerant, which is being phased out, so repairs require retrofits or full replacement planning. Newer homes in Justin tend to have builder-grade equipment that was installed fast and needs correction: undersized returns, kinked duct runs, and condensate drainage that was never sloped right.
Justin’s climate also splits the year. The summer heat index above 100°F is a genuine health risk for homes without working AC, especially for older residents. Winter cold snaps into the 20s and 30s mean a furnace failure is not just uncomfortable, it can freeze pipes. That’s why our dispatch schedules Justin jobs with local drive time in mind, not a generic metro radius. We plan repairs and installations around the actual layout of FM 156, Justin Road, and the neighborhoods off Cleveland-Gibbs Road, so our technicians arrive when they say they will.
Our Main Justin Services
Justin homeowners call us most often for AC repair when the system stops cooling in July, and furnace repair when the first cold front hits in November or December. Heat pump installation is also on the rise in Justin, where homeowners want one system that handles both heating and cooling and drops their utility load.
AC Repair in Justin
AC repair in Justin starts with a real diagnosis, not a guess. Our technicians test refrigerant charge, airflow across the evaporator coil, capacitor health, and compressor amp draw before quoting anything. Most AC repairs in Justin run $150 to $650 depending on the part, and every repair includes a written estimate before we touch the unit. The price you see is the price you pay. We also service all major brands, so if your Trane or Lennox condenser is short-cycling on a 100-degree afternoon, call us. Learn more on our AC Repair in Justin page.

Heat Pump Installation in Justin
Heat pump installation in Justin makes sense for homes without gas lines or for owners who want efficient electric heating and cooling in one unit. The installation starts with a load calculation, not a guess at sizing, because Justin’s hot summers and cold snaps punish a wrong-sized system. We handle the full job: removal of the old unit, pad and disconnect work, line set, and final charge. Heat pump installations in Justin range from $3,500 to $7,500 and include a written price before any work starts. See the details on our Heat Pump Installation in Justin page.

Furnace Repair in Justin
Furnace repair in Justin usually comes down to a failed ignitor, a dirty flame sensor, or a blower motor that has worn out after years of pushing air through Texas dust. Most furnace repairs in Justin run $150 to $700, and the part you need is often on the truck. We keep common furnace parts stocked for Goodman, Rheem, and other major brands, which means less waiting and no second scheduled visit for a simple component. If your furnace is short-cycling or the burners won’t stay lit, the repair starts with a written estimate. Get the full details on our Furnace Repair in Justin page.
